The cooling layer 80 preferably has a length of one half or more of the length of the second flow path 38 in the direction in which the second flow path 38 extends. The cooling layer 80 is preferably spaced apart from the first heat conduction member 33 constituting the cylindrical holding member 30.

Preferably, the cooling layer 80 defines a single passage through which the fragrance passes in the cylindrical holding member 30. More preferably, the inner side of the cooling layer 80 is hollow. Here, "the inside of the cooling layer 80 is hollow" means that no member other than the filter 42 provided in the suction port 40 exists inside the cooling layer 80.

In the present embodiment, the cooling layer 80 defines a single passage in the cylindrical holding member 30, and the inside of the cooling layer 80 is hollow.

In the first embodiment, the inside of the cooling layer 80 is hollow. Instead, an arbitrary member may be provided inside the cooling layer 80 so as not to significantly increase the flow path resistance of the second flow path 38. For example, a cylindrical member may be provided along the central axis of the second flow path. It is also possible to provide another cooling layer on the outer circumferential surface of the cylindrical member.

The cooling layer 80 may also include a second heat conduction member. The second heat conduction member may also be a metal. For example, the cooling layer 80 can be constructed of a metal tube. Instead, the cooling layer 80 can also be constructed of metal-bonded paper comprising paper and a metal layer bonded to the paper. For the above metal, for example, aluminum can be used. Further, instead of the aspect, the cooling layer 80 may also be a layer comprising polylactic acid (PLA). Further, the cooling layer 80 may be formed of the same material as the first heat conduction member 33 constituting the cylindrical holding member 30.

In order to increase the surface area of the cooling layer 80, the cooling layer 80 may also have a plurality of concavities and convexities. Such unevenness can be formed by subjecting the surface of the cooling layer 80 to, for example, a wrinkle treatment. By the unevenness, the cross-sectional area of the second flow path 38 can be made too small, and the heat exchange of the cooling layer 80 can be increased. The area of the face.

The inner holding member 50 may have a cup shape composed of the first side wall 51 and the bottom portion 52. At this time, the inner holding member 50 can accommodate the flavor source 90. More specifically, the bottom portion 52 of the inner holding member 50 can support the end surface of the fragrance source 90 on the non-ignition end side. Fragrance source 90 can also be comprised of a plurality of particles. At this time, the end surface on the non-ignition end E2 side of the flavor source 90 means a surface which is disposed on a portion of the plurality of particles closest to the non-ignition end E2 side, and is a surface which is in contact with the bottom portion 52 of the inner holding member.

The inner holding member 50 is disposed on the non-ignition end E2 side with the bottom portion 52 of the inner holding member 50, and is inserted into the cylindrical holding member 30 in a direction opening toward the ignition end E1 side. One or a plurality of vent holes 52A may be provided at the bottom 52. Instead, the vent hole 52A can be formed in the first side wall 51. The vent hole 52A is a portion that can be formed on the non-ignition end side E2 of the inner holding member 50. The gas system of the flavor source 90 that has flowed into the first side wall 51 passes through the vent hole 52A and flows into the second flow path 38.

The inner holding member 50 may have a flange portion 53. The flange portion 53 has a shape that protrudes from the outer circumference of the opening of the inner holding member 50 toward the outer side of the inner holding member 50. The flange portion 53 is locked to the outer circumference of the opening of the holding member 30 in a state in which the inner holding member 50 is inserted into the tubular holding member 30. Instead, the inner holding member 50 may not have the flange portion 53.

In the embodiment shown in Figs. 4 and 5, the flow path The forming member 60 includes a spiral member 61. The spiral member 61 is wound around the first side wall 51. Instead, the spiral member 61 may be attached to the inner surface of the second side wall 32. For example, the flow path forming member 60 may be composed of a metal wire formed in a spiral shape.

When the inner holding member 50 is provided in the cylindrical holding member 30 having the second side wall 32, the flow path forming member 60 connects the through port 34 and the introduction port 55 and passes between the first side wall 51 and the second side wall 32. The length of the flavor source outer peripheral section L1 of the portion corresponding to the outer circumference of the flavor source 90 in the first flow path 36 is formed to be longer than the shortest path L2 of the portion where the connecting fluid flows into the outer peripheral section L1 of the flavor source and the inlet 55. long.

In FIGS. 4 and 5, at least a part of the spiral member 61 is tied to a region between the through port 34 and the introduction port 55. Thereby, the spiral member 61 forms a spiral flavor source outer peripheral section L1 between the first side wall 51 and the second side wall 32. Therefore, the first flow path 36 is longer than the shortest path L2 between the through port 34 and the introduction port 55 when the flow path forming member 60 is not provided.

The flavor absorber 10 may have a first separator 68 that partitions the first flow path 36 from the suction port 40 (or the second flow path 38). In Fig. 2, in Figs. 4 and 5, the first separator 68 is formed by one end portion of the spiral member 61. In other words, the one end portion of the spiral member 61 is disposed closer to the ignition end E2 than the through hole 34 of the second side wall 32, and is provided between the first side wall 51 and the second side wall 32. One end portion of the spiral member 61 preferably extends in the circumferential direction of the first side wall 51. Thereby, one end portion of the spiral member 61 as the first separator 68 prevents gas from being first. The flow path 36 directly flows into the second flow path 38.

Further, the first separator 68 may not completely shield the first flow path 36 from the second flow path 38. At this time, the fluid resistance that passes through the path of the flavor source 90 among the paths of the first flow path 36 and the second flow path 38 is preferably a fluid that is smaller than the path from the first flow path 36 to the second flow path 38. The resistance is small. Furthermore, the flavor applicator may have a plurality of paths connecting the first flow path 36 and the second flow path 38. At this time, the fluid resistance of the path passing through the flavor source 90 among the paths connecting the first flow path 36 and the second flow path 38 is greater than the fluid resistance connecting the other paths from the first flow path 36 to the second flow path 38. Smaller is better.

The flavor absorber 10 may have a second separator 69 for preventing gas from leaking from the first flow path 36. The second separator 69 closes the opening on the ignition end E1 side of the cylindrical holding member 30 together with the inner holding member 50 and the combustion type heat source 70. In Figs. 2, 4, and 5, the second separator 69 is formed by the other end portion of the spiral member 61. In other words, the other end portion of the spiral member 61 is disposed closer to the ignition end E1 than the introduction port 55 of the first side wall 51, and is provided between the first side wall 51 and the second side wall 32. The other end portion of the spiral member 61 preferably extends in the circumferential direction of the first side wall 51. Thereby, the other end portion of the spiral member 61 of the second separator 69 prevents the gas from leaking from the ignition end E1 side of the first flow path 36. Further, the second separator 69 may not completely shield the gas from leaking from the ignition end E1 side of the first flow path 36.

In the above embodiment, the separators 68, 69 are formed by a part of the spiral member 61. Instead, the separator 68, 69 may also be formed of a different member than the helical member 61. Further, the separators 68 and 69 may be formed of members integrally formed on the first side wall 51 or the second side wall 32.

(action and effect)

In the inner holding member 50 and the flavor absorbing device 10 of the embodiment, the flow path forming member 60 is a length of the outer peripheral section L1 of the flavor source belonging to the portion corresponding to the outer periphery of the flavor source 90 in the first flow path 36. It is formed to be longer than the shortest path L2 that connects the portion where the fluid flows into the outer peripheral section L1 of the flavor source and the introduction port 55. Thereby, the length of the first flow path 36, that is, the length of the flow path from the through port 34 to the fragrance source 90 can be increased. Therefore, when the user does not perform the pumping operation, it is possible to suppress the fragrance from flowing out of the through-port 34 through the first flow path 36 from the flavor source 90. Thereby, it is possible to suppress the generation of the outflowing sidestream smoke without passing through the filter 42 provided in the suction port 40.

Further, the outside air is moved around the heated flavor source 90 for a long time until it reaches the fragrance source 90 from the through port 34. Thereby, heat is conducted from the heated inner holding member 50 to the outside air or the like, and the heated air is supplied to the flavor source 90. On the other hand, the outside air can also exert a function of slightly lowering the temperature of the first side wall 51 in the outer peripheral section L1 of the flavor source. Thereby, excessive heating of the flavor source 90 contacting the first side wall 51 can be suppressed. Further, from the viewpoint of more uniformly heating the flavor source 90, it is preferable to increase the temperature of the gas introduced into the flavor source 90 in advance by increasing the flavor source outer peripheral section L1.

According to one embodiment, the fluid resistance of the path through the fragrance source 90 in the path between the first flow path 36 and the second flow path 38 is connected. The fluid resistance is smaller than the path that does not pass through the fragrance source 90. Thereby, in the suction operation by the user, most of the outside air flowing from the through port 34 reaches the fragrance source 90 from the first flow path 36 via the introduction port 55, and is then generated by the fragrance source 90. The fragrance flows into the second flow path 38 at the same time.

According to one embodiment, the opening on the ignition end E1 side of the cylindrical holding member 30 is closed. Thereby, in the suction operation by the user, the outside air system is mainly introduced into the fragrance source 90 from the through port 34 via the first flow path 36.

According to one embodiment, the through port 34 is closer to the ignition end E1 side than the end of the fragrance source 90 on the non-ignition end E2 side. Thereby, in the suction operation, the user's trouble of blocking the through opening 34 with the finger is suppressed.

According to one embodiment, the introduction port 55 is provided closer to the ignition end E1 than the through port 34, and the first flow path 36 is provided only closer to the ignition end than the end of the fragrance source 90 on the non-ignition end E2 side. On the E1 side. Thereby, in the suction operation, the user's trouble of crushing the first flow path 36 with the finger is reduced.

According to one embodiment, the second flow path 38 has a cavity for diffusing the fragrance. Thereby, the fragrance by the flavor source 90 can be diffused and cooled efficiently. Further, in the present embodiment, the first flow path 36 is preferably provided closer to the ignition end E1 than the end portion of the fragrance source 90 on the non-ignition end E2 side. Thereby, since the volume of the second flow path (cavity) 38 closer to the downstream side than the fragrance source 90 can be increased as much as possible, the outer diameter of the flavor absorber can be increased without particularly increasing the outer diameter of the flavor absorber. The cooling efficiency of the gas in the second flow path 38 is further increased.

According to one embodiment, the first separator 68 that separates the first flow path 36 from the suction port 40 is provided. The first separator 68 is extendable in the circumferential direction of the first side wall 51 between the first side wall 51 and the second side wall 32. In the suction operation by the user, most or all of the outside air flowing from the through port 34 is passed from the first flow path 36 to the fragrance source 90 via the introduction port 55 by the first separator 68, and then The fragrance generated by the flavor source 90 flows into the second flow path 38 together.

According to one embodiment, the inner holding member 50 protrudes toward the inner side of the first side wall 51 and has the claw portion 54 that locks the combustion type heat source 70. The inlet 55 is formed on the non-ignition end side with respect to the contact point between the claw portion 54 of the first side wall 51 and the combustion type heat source 70. The insertion length of the combustion type heat source 70 can be appropriately controlled by the claw portion 54, and the length of the fragrance source 90 can be appropriately controlled.

According to one embodiment, the inlet 55 is adjacent to the non-ignition end side with respect to the contact between the claw portion 54 and the combustion heat source 70. Since the claw portion 54 is adjacent to the introduction port 55, the claw portion 54 and the introduction port 55 can be formed in the same process. Specifically, by projecting one of the first side walls 51 from the first side wall 51, the claw portion 54 of the lockable combustion type heat source 70 and the introduction port 55 adjacent to the claw portion 54 can be simultaneously formed.

According to one embodiment, the first side wall 51 has a tapered shape that enters the inner side of the first side wall 51 from the ignition end E1 side toward the non-ignition end E2 side. Thereby, the side surface of the combustion type heat source 70 and/or the flavor source 90 can be supported by the first side wall 51 of the tapered shape.

According to an embodiment, the inner holding member 50 has A bottom portion 52 for supporting the end surface of the fragrance source 90 on the non-ignition end E2 side is formed, and a vent hole 52A is formed in a portion of the inner holding member 50 on the non-ignition end E2 side. Further, the introduction port 55 is provided closer to the ignition end E1 than the fragrance source 90 or the fragrance source 90. The inner holding member 50 is formed in a cup shape having the first side wall 51 and the bottom portion 52. Thereby, the inner holding member 50 can hold the flavor source 90 more surely. In particular, when the flavor source 90 is formed of a plurality of fragrance sheets, such as granular sheets, the inner holding member 50 can also maintain the flavor source 90.

According to one embodiment, the second side wall 32 covers at least a part of the first side wall 51 and has a heat conduction member 33 that extends toward the non-ignition end E2 side than the first side wall 51. The heat generated by the combustion type heat source 70 can be efficiently conducted to the fragrance source 90 by the heat conduction member 33. Further, since the heat conduction member 33 extends toward the non-ignition end E2 side from the first side wall 51, the heat of the heat conduction member 33 is radiated to the end portion before the protrusion from the first side wall 51. Thereby, the first side wall 51 is suppressed from being excessively heated. The heat conduction member 33 is preferably formed of a material having a higher thermal conductivity than the first side wall 51. The first side wall 51 is preferably formed of a material having higher corrosion resistance to the carbon material than the heat conduction member 33.

According to one embodiment, the inner holding member 50 is integrally formed by the heat conducting member. Thereby, the inner holding member 50 can function to conduct heat generated by the combustion type heat source 70 to the flavor source 90.

[Second Embodiment]

Hereinafter, the flavor applicator 10A of the second embodiment will be described with reference to Fig. 11 . In addition, the same components as those of the first embodiment are denoted by the same reference numerals. In the following description, differences from the first embodiment will be mainly described.

In the second embodiment, the through hole 34 formed in the cylindrical holding member 30 is provided closer to the non-ignition end side E2 than the end portion of the fragrance source 90 on the non-ignition end E2 side. The first flow path 36 extends from the through port 34 toward the ignition end E1 side. A pipe member 84 is provided inside the cylindrical holding member 30. The pipe member 84 is partitionable between the first flow path 36 and the second flow path 38 and extends from the position of the through hole 34 to the first side wall 51. The first flow path 36 passes between the first side wall 51 of the inner holding member 50 and the second side wall 32 of the cylindrical holding member 30 and reaches the introduction port 55.

The section in the vicinity of the through port 34 of the first flow path 36 can pass through the separator 68 and be adjacent to the second flow path 38. The separator 68 includes a resistance member 82 that directly seals a gap between the first flow path 36 and the second flow path 38. The resistance member 82 does not fluidly completely shield the first flow path 36 from the second flow path 38, and increases the fluid resistance of the path from the first flow path 36 directly into the second flow path 38.

The fluid resistance directly entering the path of the second flow path 38 from the first flow path 36 via the resistance member 82 (see the arrow F6 in FIG. 11) is preferably higher than the flow rate from the first flow path 36 via the fragrance source 90. 2 The path of the flow path has greater fluid resistance. In other words, the separator 68 is configured to pass the fragrance source 90 in the path connecting the first flow path 36 and the second flow path 38. The fluid resistance of the path may be less than the fluid resistance of the path that does not pass through the fragrance source 90. Thereby, a large amount of air flowing into the first flow path 36 can be guided to the fragrance source 90.

Further, the separator 68 is configured such that the fluid resistance of the path through the fragrance source 90 in the path connecting the first flow path 36 and the second flow path 38 is smaller than the fluid resistance of the path through the fragrance source 90. It can reach one of the first flow path 36 and/or the through port 34.

As described in the second embodiment, a plurality of paths for connecting the first flow path 36 and the second flow path 38 may be provided. At this time, the fluid resistance of the path through the fragrance source 90 among the paths connecting the first flow path 36 and the second flow path 38 is preferably the smallest.

A protrusion or groove 66 is formed. Formed integrally on the inner surface of the second side wall 32 The protrusion or groove 66 can also be, for example, a spiral shape. In this case, the length of the outer peripheral section of the flavor source belonging to the outer periphery of the flavor source 90 in the first flow path 36 may be a portion that is smaller than the portion where the connecting fluid flows into the outer peripheral section of the flavor source and the introduction port. The shortest path of 55 is still long.

Further, in the case where the cylindrical holding member 30 has the heat conducting member facing the first flow path 36, a projection or a groove as a flow path forming member may be formed on the inner surface of the heat conducting member.
